EPGT040102 SH725 Tungaloy indexable turning insert – ISO 040102, 75° rhombic

A EPGT040102 SH725 indexable insert designed for external and internal turning, optimised for small tools and variable engagement conditions

• ISO‑standard rhombic insert 75°
• Coated cemented carbide SH725
• 0.2 mm nose radius for fine finishes
• Suitable for external and internal turning

Consistent cutting performance with a tough, edge‑stable grade

The SH725 grade is a coated cemented carbide developed for toughness and edge stability, giving reliable performance where cutting conditions change frequently. As a consequence, chip formation remains controlled even with small‑diameter tools or intermittent cuts; this reduces the risk of edge chipping and extends effective tool life. The insert is intended specifically for turning operations and delivers predictable behaviour in dynamic machining, supporting efficient cycle times and fewer unscheduled tool changes.

Geometry that supports accuracy and surface quality

The rhombic 75° relief and the 0.2 mm nose radius combine to offer a balance between rigidity and finish capability. The moderate nose radius helps achieve fine surface quality without compromising on strength at the cutting edge. The compact 1.59 mm thickness and a cylindrical hole with single‑side countersink (40°–60°) provide secure clamping and repeatable seating in compatible toolholders, reducing vibration and enhancing dimensional stability on the workpiece. These attributes are especially useful when tight tolerances and consistent finishes are required.

ISO compatibility and clear holder selection criteria

As part of an ISO‑standard insert series, compatibility with a holder is governed by form, 11° clearance angle, tolerance class, fixing method, size and thickness. This standardisation simplifies integration into existing tool systems: choose a matching external holder or boring bar, plus the correct clamp set and replacement screws for secure assembly. The ISO basis permits readily available clamping systems to be used, supporting quick insert changes and consistent positioning across multiple tools.

Practical application focus and production benefits

Designed for turning, the insert excels where tool engagement varies or space constraints demand compact tooling. The single‑sided chipbreaker geometry supports predictable chip flow for a range of operations, while the overall design reduces set‑up complexity. For manufacturing environments prioritising uptime, the combination of a robust grade and standardised geometry means fewer interruptions and steady machining performance, contributing to overall process reliability and efficient throughput.

FAQ

What turning operations is this insert intended for?
The EPGT040102 SH725 Tungaloy indexable insert is intended for both external and internal turning, delivering stable performance where engagement conditions vary.

Which geometry details are most relevant for setup?
The insert features a 75° rhombic shape, a 0.2 mm nose radius and an 11° clearance angle; these dimensions are key when matching the insert to a holder and setting cutting parameters for the TUN6737249 item.

How should a compatible holder be chosen?
Holder compatibility depends on form, clearance angle, tolerance class, fixing method, size and thickness; selecting an ISO‑compliant holder and the correct clamp set ensures secure seating for the EPGT040102 SH725 insert.

What does the SH725 grade offer for production?
SH725 is a tough, edge‑stable coated carbide grade tailored for turning, especially effective with smaller tools and fluctuating cut engagements, providing reliable chip control and longer edge life.

Is this insert suitable for fine finishing?
Yes; the 0.2 mm nose radius combined with the insert’s rigidity and secure clamping enables fine surface finishes while maintaining cutting edge integrity for repeated operations.
